CLAMPING-JOINT FOR DRILLS. I

To all whom it may concern;

Be it known that I, CHARL S W. GUTTZEIT, a citizen of the United States, residing in; High Bridge, in the county of Hunterdon and State of New Jersey, have invented certain;

new and useful Improvements'in Clampingthe hollow shafting or pipes of large diameters, such asusedin rotary drills and similar; devices. 5

The object of, the present invention is tol provide a clamping structure of the class re ferred to that can be simply and rapidly con-l nectedand will retain the sections together? with thenecessary strength 'andrigidity and% which also can be very readily and quickly disconnected when it is desired to separatef the sections. E

In the drawings representing one embodiment of -my invention, Figure l is an end ele-j vation of two connected pipe-sections. 2 represents an axial section through the} pipe connection. Fig. 3 is a side elevation showing two pipe-joints in reduced scalel Fig. 4 shows in perspective the inner arrangement of one of the pipe-sections. Fig. 5 is a similar view of the complemental pipe-section. Fig. 6 shows a key for preventing rela.

' tive rotation of the connection-sections.

Fig. 7 shows in perspective a half of a 'segmental ring with the locking-segment partly inserted. Fig. 8 is a transverse section through the wedge-segment on the line 8 8 of Fi '7, and Fig. 9 shows the wedge-pin for lodking the wed e-segment in position.

Heretofore it as been the practice to con nect pipe-sections of large diameter for drillrods and similar purposes by having internal flanges that are secured together by bolts. In such construction it is necessary to use a large number of bolts, which requires con-h siderable time to place in position. The bolts have to be large and very strong, as the strain, both tensile and shearing, is excessive. Furthermore, as these pipes are immersed in water for long periods the bolts become rusted in place, so that when it is required to disconnect the sections it is practically impossible to unscrew and remove the bolts, and they must be cut out and new bolts used. Furthermore, even to unscrew such a num- Specification of Letters Patent.

5 her ofbolts would re uire considerable time.

To overcome these e'fects and others, the present invention provides a segmental coupling ring or member that is provided with. 'means for expanding it to effect engagement between the ring and the pipe-sections. To

clamp the sections together, one of the.

rlng-segments has a wedge engagement with the ad'acent segments, whereby the ring'is expandedand clam ed in positionby the simple-act of merely riving home' this wedgesegment. 'Awedge-pin may be also used to connect the wedge-segment with one adjacent segment of the ring to lock the segment in position. By the mere operation of assembling the ring-segments in position, then inserting the wedge-segment to expand the ring, and then inserting the wedge-pin the coupling is effected. To disconnect the pipe-sections, all that is required is to drive out the wedge-pin to unlock the wedge-segment and then remove the wedge-segment, whereupon the remaining segments of the ring can be removed to free the pipe-sections. Should the wedge-pin become rusted fast, it can be very quickly cut off by a sawor coldchisel. The torsional strain between the pipe-sections is taken by one or more keys inserted in alining'slots in the internal flanges of the pipe-sections.

Referring now to the drawings, each of the pipe-sections A and B is provided with an internal flange. adjacent the end portion. The j section A has a ring member 12 suitably se cured inside at one end, as by rivets 13,

which ring has an internal flange portion 14,

the outer portion 15 being made slightly tapering, as shown. The pipe-section B has a ring 16, provided with aflange portion 17, that extends inward, and, also projects beyondthe end of the pipe, as shown in Fig. 4. This flange extension is arranged to fit into the portion 15 of the ring 12 when the pipe sections are brought together, as shown in Fig. 2, from which it will be seen that the two flange portions 17 and 14 are abutting and are in alinement. To prevent relative rotation of the pipe-sections, the flange 16 is provided with slots 18 and 19, that register, respectively, with slots 20 and 21 in the flan e 14. Suitable keys -22 are fitted in these registering slots and of the sections.

A clamping ring is formed of a number of segments and is shown as comprising four segments 23, 24, 25, and 26, which are comprevent lateral movement TOO 7 shown rately in Fig. 9.)

plemental to constitutea complete aimular ring, as shown. formed of a greater or less number of complemental sections. 'The ring as a whole is provided with an external flange 27 at one end and a similar flan e 28 at the other end, as shown in Fi s. 2 am 7 but the segment 26 is not provide with the flange portion 28, as shown in Fig. 8.

in Fig. 7, and the abutting end 30 of the ring-segment 25 is correspondingly inclined, as shown. The other end 31 of the ring-segment 26 is inclined, but in the opposite direction to that of the end 29, thereby forming a wedge member of this segment.

The segments are so formed that when the wedge-segment 26 is driven home it will aline with the other segments, as indicated in Fig. 2.

It is desirable'to lock the wedge-segment in this position by suitable means. The segment 26 is shown as provided with an extension 33, contalnmg an aperture 34, into which is inserted. a wedge-pin 35.

The key 22 is inserted in a recess portion 37 in the rear of the wedge-segment 26 before the latter is placed in position and will be thereby retained in position to lock the segments against lateral movement by engagement with the walls of the slots 18 and 20. Any other keys that are used to engage similar registering slots in the flanges 14 and 17 are retained in position by being located between the flanges 27 and 28 of the ring-segments.

To facilitate the handling of the ring-segments, which are rather cumbersome with such large structures, apertured lugs 38 may be formed on the segments to be engaged by suitable lifting devices.
